IMPROVEMENT IN Fences.

- To. all whom filma/y concern:

Be it known that I, JOSEPH B. TEDROW, o f Chillicothe, in the county of Ross, and State of Ohio, have invented certain new and useful Improvements in Fences; and I do hereby declare' that the followin gis a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of this specification;

1 This inventidn relates to improvementsin fences, the object of which is to render them cheaper of construction, more durable, and to arrange them so that they may be Jprotected from floods, when located in river-bottoms subject to be overowed.

It consists in providing sectional posts, vto be constructed partly or wholly of metal, and joining the sections by hinging themy together. .l Figure l represents a side elevation of one panel of a fence, constructed with iny improved posts.

Figui-e2 represents edge views of the posts. Similarjletters of reference indicate corresponding parts.

I purpose to construct the posts partly of iron and wood, and in sections, and sometimes wholly of iron.

For-fences to be used on lowriver-bottoms, that are subjectto be overlowed, I purpose to construct the posts in two parts, A and' B, and hinge the two parts together with a: double joint, as represented at G, and

4 make the pintle of the up-stream side of wood, so that lif the water rises suddenly, and without sufficient warnling to admit of their being withdrawn, they will break,

and allow the fence to swing down to present only an edgewise resistance to the current.

After the water has subsided, they may he raised up again, and the joints fastened as before.

The part B may be made of cast-iron, and of wedgeform, so as to be drivenrreadily into the earth.

The part A may either be made of wood or metal, as preferred.

' If made of iron, the cross-pins a may be cast with the other portion,and the transverse slots b may be made in-them, to save metal, and to allow a free circulation of air for the ends of the boards or rails.

D representsl the form of post which I prefer for the middle posts, as possessing the greatest amount of strength with the least amount of metal.

The boards or rails for the top joint may be tapered at the lends, as represented at E, so as to lap each other,- and may be joined together by pins, or nails, F. I claim as new, and desire to secure "by Letters Patent- Y 1. Fence-posts, made in sections A and B, and

hinged together, substantially as and for the purpose v
